思路一：关闭监听日志，删除已有日志

1、检查监听日志状态

2、修改listener.ora，增加下方标红行

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
INBOUND_CONNECT_TIMEOUT_LISTENER = 0
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = WIN-database)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = D:\app\Administrator
Admin_Restrictions_LISTENER = OFF

3、设置log_status off

CMD中执行lsnrctl

4、删除listener.log

删除 D:\app\Administrator\diag\tnslsnr\WIN-database\listener\trace\下日志释放空间

5、参考MOS文章

TNS-12508 When Issuing Any SET Command For The Listener (文档 ID 238312.1)

思路二：脚本定期删除

采用批处理清理脚本+系统任务调度定期检查清理监听日志文件，避免文件达到4G

脚本如下:

@echo off
::该脚本实现当监听日志文件大小达到一定大小(400M)时自动备份，防止达到4G时引发监听异常问题
::注意指定listener.log文件路径
set ListenerLogFile=F:\app\TheOne\diag\tnslsnr\WIN-database\listener\trace\listener.log
::指定日志文件达到多大时进行删除，默认400M
set FileSize=419430400
set CurDate=%date:~0,4%%date:~5,2%%date:~8,2%
set CurTime=%time%
set CurDateTime=%CurDate%_%CurTime:~0,2%%CurTime:~3,2%%CurTime:~6,2%
::停止监听写日志
lsnrctl set log_status off
FOR /f "delims=" %%i in ("%ListenerLogFile%") do (
IF %%~zi gtr %FileSize% (ECHO 正在执行备份。。。 && ren %ListenerLogFile% listener.log.%CurDateTime%) else (IF %%~zi lss %FileSize% (ECHO 不执行清理 ) ))
::开启监听写日志
lsnrctl set log_status on
::重载监听日志
lsnrctl reload
